Crop damage caused by frost looks a lot like copper deficiency. Leaf damage extends back from the tip of the leaf. Damage to seed heads can be easily confused too. Other than similar symptoms, there’s little evidence yet to link frost and copper deficiency.
The location of damage can help with […]

Having sufficient potassium reduces crop damage in frost events. Field trials in Western Australia showed benefits from potassium in wheat and canola. Richard Bell is a researcher at Murdoch University. In this video he explains:

Crops respond more to potassium fertiliser in seasons that stress the plants with drought or frost […]

Crops may need extra Potassium when they under stress from drought or frost. There is a theoretical basis, and now GRDC funded research is looking into whether applying additional potassium is worthwhile when plants are under stress.
Getting the right combination of drought and frost conditions to get meaningful results from […]
